Abstract

Carbon neutrality targets rely on the flexible, fast-response characteristics of batteries, and the high energy density and clean byproduct of hydrogen. However, the potential role of battery and hydrogen circular economies in the carbon neutrality transition remains uncertain. In this study, a future clean power grid and its impact on the lifecycle carbon footprint of battery and hydrogen circular economies have been predicted. A database of the lifecycle carbon footprint is set up from raw material to recycling. Additionally, a carbon intensity map of lifecycle stages of batteries and hydrogen storage across climate regions in China is provided. The proposed zero-energy paradigm is economically feasible with the obtained levelized net present value ranging from 0.0119 US$ per kWh_e (Kunming) to 0.0574 US$ per kWh_e (Guangzhou). The findings aim to clarify the role of battery and hydrogen circular economies in the carbon neutrality transition and provide a comprehensive analysis of hydrogen and battery technologies for policy decision-makers.

电池和氢驱动的综合低碳系统的生命周期碳强度。

碳中和目标依赖于电池灵活、快速响应的特性，以及氢的高能量密度和清洁副产品。然而，电池和氢循环经济在碳中和转型中的潜在作用仍然不确定。在本研究中，预测了未来清洁电网及其对电池和氢循环经济生命周期碳足迹的影响。建立了从原材料到回收的全生命周期碳足迹数据库。此外，还提供了中国不同气候区域电池和氢储存生命周期阶段的碳强度图。所提出的零能耗模式在经济上是可行的，所获得的平准化净现值从0.0119美元/千瓦时（昆明）到0.0574美元/千瓦时（广州）不等。研究结果旨在阐明电池和氢循环经济在碳中和转型中的作用，并为政策决策者提供氢和电池技术的全面分析。
